I have a TF and MF and control them both with a Midi Moose. You have to set the first effect's midi output to Thru. This allows the Midi Moose (or whatever you use) to pass the midi program changes to the second effect. It works flawlessly. The learn mode on the midi program rcv section of the Eventides make programming simple. If you want your midi controller program #1 to add a delay (assuming the TF is the second effectt) you would program the MF to bypass when program #1 is selected and th TF to activate the bank and program that has the delay setting you want. At the same time I am also changing amp channels on my Mark V with the same midi controller and a Voodoo Labs Control Switcher.
